I-PCB Ethuthukisiwe Yamadivayisi Aphathwayo Asebenzisa Imvamisa Ephakeme: Ukuhlanganiswa Okuphelele Kwenqubo Yokuxhuma i-Rogers + FR4 TG170, HDI, kanye ne-Resin
Ziyini izinqubo zokuxhuma i-Rogers+ FR4 TG170, i-HDI kanye ne-resin kuma-PCB aphathwa ngesandla asebenza ngezikhathi eziningi?
I-PCB yethu yamadivayisi aphathwa ngesandla asebenzisa imvamisa ephezulu isebenzisa izinto ezihlukile nezinqubo ezithuthukisiwe. Izinto zikaRogers zaziwa ngokusebenza kwazo okuhle kakhulu kukagesi osebenzisa imvamisa ephezulu. Zine-dielectric constant ephansi kanye nenani eliphansi lokulahlekelwa, okunganciphisa ngempumelelo ukuncishiswa kanye nokuphambuka kwezimpawu ngesikhathi sokudlulisa, okwenza zifaneleke kakhulu ekucubunguleni izimpawu ezisebenzisa imvamisa ephezulu. I-FR4 TG170 iyi-epoxy laminate eqiniswe ngefayibha yengilazi esebenza kahle kakhulu enezinga lokushisa eliphakeme lokushintsha kwengilazi (TG170). Lokhu kuyenza ikwazi ukugcina izakhiwo ezinhle zomshini kanye nokufakwa kukagesi ngisho nasezindaweni ezishisa kakhulu, okuhlinzeka ngokusekelwa kwesakhiwo okuzinzile kwe-PCB.
Ubuchwepheshe be-HDI (High Density Interconnect) buvumela ukuxhumana kwesekethe enobuningi obukhulu ngaphakathi kwesikhala esilinganiselwe. Ngokuklanywa kwama-pitch amancane nama-via, ubuchwepheshe be-HDI bungahlanganisa izingxenye eziningi ze-elekthronikhi, kwandise ubuningi bokusebenza kwe-PCB. Ngesikhathi esifanayo, bungaphinde bufinyelele ekudlulisweni kwedatha ngesivinini esikhulu ukuze kuhlangatshezwane nezidingo zamadivayisi aphathwa ngesandla anobuningi obukhulu ukuze kusheshiswe ukucubungula idatha.
Inqubo yokuxhuma i-resin ihilela ukugcwalisa ama-via e-PCB nge-resin bese uyilungisa. Le nqubo ayivimbeli nje kuphela ukushiswa kwengqimba yethusi ngaphakathi kwama-via, ithuthukise ukuthembeka kokuxhumeka kukagesi, kodwa futhi ithuthukisa ukusebenza kokushabalalisa ukushisa kwe-PCB. Njengoba i-resin inomoya omuhle wokushisa, ingadlulisa ukushisa ngempumelelo, iqinisekise ukuzinza kwe-PCB ngesikhathi sokusebenza kwemvamisa ephezulu.
Ukusebenza Okuhle Kakhulu Kwemvamisa Ephakeme: Izici zokulahlekelwa okuphansi kwezinto zikaRogers kanye nekhono lokudlulisa idatha ngesivinini esikhulu lobuchwepheshe be-HDI kwenza amadivayisi aphathwa ngesandla avame kakhulu ukuthumela nokwamukela amasignali ngokunembile ezindaweni eziyinkimbinkimbi ze-electromagnetic, kunciphisa ukuphazamiseka kwesignali kanye namazinga amaphutha e-bit, kanye nokuthuthukisa ikhwalithi yokuxhumana.
Ukuxhumeka Kukagesi Okuthembekile: Inqubo yokuxhuma i-resin iqinisekisa ukuthembeka kokuxhumeka kukagesi kuma-via, ivimbela ama-circuit amafushane esignali kanye nama-circuit avulekile. Ngesikhathi esifanayo, ukwakheka kwesekethe encane yobuchwepheshe be-HDI kunciphisa nokushintsha kwe-impedance ngesikhathi sokudluliselwa kwesignali, okuqinisekisa ubuqotho besignali.
Ukusebenza Okuhle Kokushabalalisa Ukushisa: Izinga lokushisa eliphakeme lokushintsha kwengilazi le-FR4 TG170 kanye nezinzuzo zokushabalalisa ukushisa kwenqubo yokuxhuma i-resin kwenza i-PCB ikwazi ukuqeda ngempumelelo ukushisa okukhiqizwa ngesikhathi sokusebenza kwemvamisa ephezulu, igweme ukwehla kokusebenza kanye nokwehluleka okubangelwa ukushisa ngokweqile, futhi yandise impilo yesevisi yamadivayisi aphathwayo asebenzisa imvamisa ephezulu.
Umklamo Oqinile Wesakhiwo: Amandla okuhlanganisa isekethe ephezulu yobuchwepheshe be-HDI avumela i-PCB ukuthi ifeze imisebenzi eminingi ngaphakathi kwesikhala esilinganiselwe, ihlangabezane nezidingo zomklamo wamadivayisi aphathwa ngesandla avame kakhulu ukuze kube lula ukuwasebenzisa futhi abe lula, futhi ithuthukise ukuphatheka kalula kanye nokusetshenziswa kalula kwemishini.
Ukulawulwa kwekhwalithi kubaluleke kakhulu ekukhiqizweni kwama-PCB amadivayisi aphathwa ngesandla asebenzisa imvamisa ephezulu. Ama-PCB ethu ahlolwa kanzima ukuze ahlangabezane nezidingo eziqinile zamadivayisi aphathwa ngesandla asebenzisa imvamisa ephezulu. Ukuhlolwa kufaka phakathi:
